Abstract:

Caco-2 cell monolayers were used as a model of the intestinal epithelium to investigate the recovery profile from the transport-enhanced state induced by the transport enhancers, capric acid sodium salt (C10FANa) and capric acid monoacylglycerol (C10MG). The transepithelial electrical resistance, MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide) assay, and lactate dehydrogenase (LDH) release rate were investigated. The cell monolayer recovered depending on the concentration of the enhancer and on the exposure time. The MTT assay revealed that the cells recovered their mitochondrial dehydrogenase activity without proliferation. The cell monolayer exposed to C10FANa released LDH to both the apical and basolateral sides, but to C10MG, only to the apical side. The results were compared with those for SDS and taurocholic acid sodium salt, and the effect of C10FANa was found to be different. These results suggest that the damage by MCFA compounds is recoverable and that the recovery can be assessed by an MTT assay, but that the LDH-release behavior is different among the enhancers.
